When the Original is activated, a pulsating (or flashing) light is visible along the entire length of the light strands. The inventors decided the light should be pulsating so that it would attract the occupant’s attention in the event of an emergency. You can find more information about the usefulness and necessity of a pulsating light at Scientific Justification.
In America, flashing lights, in addition to audible signals, are an obligatory component of a fire alarm system as they reinforce the effect of the alarm on the occupant. Furthermore, the flashing light will alert deaf or hard-of-hearing people to an emergency.
Around 3.5% of the population in the Netherlands uses a device to enhance hearing, so during an emergency, a pulsating light will be of great value to this group in particular.
Colour of the lighting strands
During an emergency the strands emit a blue-green colour. The reasons for this are:
Colour blindness: around 8.25% of the male population and 0.5% of the female population suffer colour blindness to a greater or lesser degree. This amounts to approximately 4.5% of the total population. The colour green is commonly associated with safety. Approximately 80% of colour blind people have difficulty distinguishing colours in the red/green ranges, seeing green as a shade between green and grey. Blue is perceived as blue by about 98% of colour blind people.
Blue is usually associated with a warning signal, for instance the flashing lights on emergency service vehicles or the floor path systems on the floors of aircraft.
The perception of blue requires less energy from the receptors in our eyes than other colours, making it most noticeable in stressful situations.
In the light strand technology used by LightSaver, the blue-green colour has been shown to provide the best light output per metre compared to other colours
On request we are able to supply special or large orders of light strands in other colours if a specific situation so requires.
